AbstractAll commands issued by the brain travel along nerves to respective muscles and there initiate the appropriate contraction. At the junction of nerve and muscle, the neuromuscular junction, the nerve cells and muscle cells are separated by a cleft, across which a chemical, acetylcholine, moves in small quanta at great speed.

Neurotransmitters in the Brain
1989The brain is the pacemaker of the human body. If this pacemaker does not function life is not possible. In the brain there are more than 10 billion neurons. Each neuron makes more than a thousand contacts. The axons of the neuron branches ramify into several end terminals which are in contact with other cell bodies and dendrites. The propagation of the

Neurotransmitters and cognition
2006Cognition deficits have receivedmuch attention over the last two decades. The severe impairment of cholinergic function in dementias, particularly in age-related cognitive decline andAlzheimer’s disease has been indicated. However, loss of cholinergic activity may play a key role in the cognitive symptoms but it cannot clearly demonstrate the entire ...

Chemical transmission is the fundamental mode of communication in the nervous system that depends on receptors in the plasma membrane for sensing released neurotransmitter and for producing an appropriate, well-timed response. Two distinct types of receptors mediate this process: ionotropic and G-protein coupled.
